Which activity is part of Construction Commissioning (Planning)?

• A. Review existing documentation
• B. Complete commissioning report
• C. Balance systems, document and verify the results
• D. Carry out a survey to gather and document needed information

Answer: (D)

The key idea is that planning in Construction Commissioning revolves around collecting the information you’ll need to design and execute the testing and verification work. Carrying out a survey to gather and document the needed information directly provides the factual basis for the commissioning plan: it captures site conditions, installed equipment, control sequences, interfaces, project requirements, and owner expectations. With this data, you can define scope, responsibilities, test procedures, acceptance criteria, and a realistic schedule, setting up the entire commissioning effort for successful execution.

Reviewing existing documentation is still important, but it’s typically about verifying what’s already on record rather than actively gathering new information to shape the plan. Completing the commissioning report belongs to the close-out phase, and balancing systems, documenting and verifying results happens during the testing and verification phase rather than planning.
